This part of ISO 2768 is intended to simplify drawing indica-tions and specifies general geometrical tolerances to control those features on the drawing which have no respective in-dividual indication. It specifies general geometrical tolerances in three tolerance classes.
This part of ISO 2768 mainly applies to features which are pro-duced by removal of material. Its application to features manufactured by other processes is possible; however, special examination is required to ascertain whether the customary workshop accuracy lies within the general geometrical toler-ances specified in this part of ISO 2768.
